Stuart Welcome Arch, Historic gateway in Jensen Beach, Florida, United States

Stuart Welcome Arch is a gateway spanning County Road 707 between Northeast Dixie Highway, featuring two towers connected by a horizontal beam that displays directional signage. The structure sits prominently at ground level where local traffic moves through daily.

Built in 1926 during the Florida land boom, the arch marked the then-town lines of incorporated Jensen and Stuart and heralded Stuart as a "Gateway to the Gulf of Mexico," tied to the opening of the Okeechobee Waterway. After Jensen went bankrupt and was dissolved in the Depression, the state forced Stuart in 1933 to retrocede most of its area north of the St. Lucie River, leaving the arch in unincorporated Martin County. It was listed on the National Register of Historic Places on September 15, 2004.

The arch's lettering has changed with the fortunes of its neighbours: in 1998 its faces read "Welcome to Rio" and "Welcome to Jensen Beach," and early-2000s restoration work replaced these with the original "Stuart" and "Jensen" even though neither town then bordered the structure.

The arch sits directly on County Road 707 and is easily accessible by foot or vehicle since it crosses a main road. Those stopping to photograph or examine it closely should be aware of passing traffic in the area.

The structure has undergone several transformations over the decades, including a repainting in pink during 1994 and various repairs to the crossbeam following weather damage and vehicle impacts. These changes show how the gateway has adapted alongside the community's evolution.
